What is a fraction?</h3>
- A fraction is a portion of a whole or, more broadly, any number of equal parts.
- In everyday English, a fraction describes the number of parts of a specific size, such as one-half, eight-fifths, or three-quarters.
To find how much money would Alina has if her mother gave her 1/6 more of what she had at first:
Alina has 3/5 much money as Edna.
Edna has $32.
Alina's mother gave her more 1/6 or 3/5.
So, first, we will find 1/6 of 3/5.
Now, add 3/30 to 3/5.
Hence, Alina has 21/30 as much money as Edna.

Step-by-step explanation:
3x=28+y
x=28+y÷3
then puttingx=28+y÷3
3x=14+y
3(28+y÷3)+y=14
84+3y+3y=42
3y+3y=42-84
y=-42÷6
y=7
so putting y=-7
3x-y=28
3x-7=38
x=38+7÷3
x=15
